Well, let’s face
it, Linux is cool. Using Linux makes you look cool. But, for new users, may be not so much. Typing
those long commands can be a little intimidating and may even scare
them off.
Wouldn’t it be awesome if there was a way, so that you won’t have to type long
commands? Or even better, to create your own new commands by which you can do a
lot of stuff?
You are in luck, because Aliases help you with that and much more.

What are Aliases
anyway?Alias, as the
name suggests is an alternate form of a previously existing command(s). So
basically you are creating your own custom command with which you can do a lot of functions. Enough with the
definitions, let’s see an example.
Say you want to go to the Desktop folder. You would have to do something like this,

[dsp@freblogg]$:~ cd /home/dsp/Desktop

How about instead
of typing all that, you just say desk like this and it takes you to
Desktop?

Caesar's cipher is one of the most popular encryption techniques in Cryptography. It is also referred to as Caesar's shift cipher or simply Shifting cipher. It is said to be widely used in private communications of Julius Caesar. The encryption of the plain text is done by shifting the letters by a previously agreed number. So, after a shift of 2, 'a' becomes 'c', 'b' becomes 'd' and so on..

This article will show you a program that can be used to decrypt the cipher text encrypted using this method. To decrypt, you need to know the key which is the shift used to encrypt. Using the key we'll just do the reverse of encryption to get the Plain text. And, we'll program all that.

Quine in programming terms is a program which outputs its own Source code. These are self-replicating programs and are very popular in the programming community. So, in this article we will see how we can achieve this.
This problem may sound complex, but this is actually quite easy and simple. So, the way we proceed with this is by opening the source file from the program and print out each and every character.
Sounds simple, doesn't it? Lets code it.
Things you need to know for this : Usage of File Pointers

Procedure: Lets break down the approach step by step

Open the current file (fopen()) using a file pointer (in Read Mode)

Read characters one after the other and print them until you reach the end of the file (EOF)

Close the file

To open the file we'll use the fopen() function which takes in two parameters, the location of the file and mode of opening (Read/Write). Fortunately for us, there is a macro in C, to give us file's location, called _FILE_ macro. Using this we can get the location/path of the current file.
